The emission of nitrogen oxide (NOx), monoxide (NO) and carbon (CO) from vehicle exhaust gas generates an adverse effect to the environment as well human health. Therefore, need reduce such is urgent. decrease can be achieved through use catalytic converter. This study explains application converter prepared activated enhance activity its adsorption ability. was derived banana peels after heati...

This paper presents a Single-chamber Microbial Fuel Cell (SMFC) design by utilizing soil as substrate with two sets of electrode combinations, which are graphite-activated carbon and copper-zinc different sizes. It was found that graphite activated produced greater power density compared to copper zinc. Moreover, it observed the cloth bigger surface area 51cm2, resulted in higher 904mW/m2. To f...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

for beneficiation of converter slag, the role of surface phenomena on slag composition was studied. this work includes some experimental data, which were measured for basic oxygen steel (bos) slag in isfahan steel plant. all data were collected on site in the plant. the results support the idea that surface activity plays a major role in converter slag formation. it was also a new finding that ...
